cubicweb-vcreview #1872859 'mark as done' button on a patch task leads to a json page [resolved]

Clicking the 'mark as done' button on a patch's task redirects to a "/json?rql=Any X%2CAA WHERE X eid NNN%2C X is Patch%2C X modification_date AA&vid=vcreview.patch.tab_main&fname=view" sort of page, which is probably not what is wanted. I think this is a relatively recent regression.
